I was ready to pull the trigger on a 26 until I found out about conversion barrels. You can get a 27, buy a conversion barrel to a 9mm making it a 26. I figured great...2 in 1 is better than 1. I have heard the 27 is great and I've heard it's very uncomfortable to shoot due to being 40 s&w and being small. I can't try it then buy it due to my states laws. Glock told me not to shoot 9mm with a conversion barrel with the 27. I'd have to swap out parts like the firing pin etc. I don't know if that's what they have to say for legal reasons or it that is really the case. If that's the case I won't get the 27 and get the 26 instead. I wanted the 26 because it will be cheaper at the range to shoot 9mm. With the 27 and conversion barrel I figured plink 9mm and carry a better .40 round but now I'm not sure what to do. All I have now I s the 43 and a 30. I don't shoot the 30 as much because .45 is costly and the 43 isn't much of a range toy. I was just looking for some words of wisdom to finalize my pick. Anyone else use the conversion barrel only and have any issues or change the other parts to do so? Thanks for listening and any advise is appreciated.
